Predictive maintenance systems take a more and more important place in increasing the reliability of industrial equipment, of productivity and reducing production costs. There’s a constant focus to develop new system architectures and in using the latest numerical methods and algorithms in developing more and more reliable predictive maintenance systems. Based on recent results in using Shepard local approximation operators defined in Riesz MV-Algebras for IoT devices signals processing, in this article we propose a new architecture for a predictive maintenance system by adding an extra layer (denoted Data Validation Layer). This new layer is processing the acquired signals by sensors such that to provide to the predictive algorithms a complete and validated data set. The proposed architecture was validated by implementing and testing a predictive maintenance system that is monitoring the bearings of industrial equipment using temperature sensors.KeywordsPredictive maintenanceIoTIndustrial equipmentSensorsRiesz MV-Algebras

Data‐driven fault diagnosis approaches have been widely adopted due to their persuasive performance. However, data are always insufficient to develop effective fault diagnosis models in real manufacturing scenarios. Despite numerous approaches that have been offered to mitigate the negative effects of insufficient data, the most challenging issue lies in how to break down the data silos to enlarge data volume while preserving data privacy. To address this issue, a vertical federated learning (FL) model, privacy‐preserving boosting tree, has been developed for collaborative fault diagnosis of industrial practitioners while maintaining anonymity. Only the model information will be shared under the homomorphic encryption protocol, safeguarding data privacy while retaining high accuracy. Besides, an Autoencoder model is provided to encourage practitioners to contribute and then improve model performance. Two bearing fault case studies are conducted to demonstrate the superiority of the proposed approach by comparing it with typical scenarios. This present study's findings offer industrial practitioners insights into investigating the vertical FL in fault diagnosis.
... However, with the significant drawback of mode mixing of EMD, data with similar scales may appear in different intrinsic mode functions (IMFs) (Zhang and Hong, 2019). To overcome this defect, ensemble empirical mode decomposition (EEMD) is proposed by adapting the Gaussian white noise and widely used in many fields, such as hydrological forecasting and mechanical fault diagnosis (Zhang et al., 2018;Ali et al., 2020;Faysal et al., 2021;Wang et al., 2021). For example, Ali et al. (2020) investigated the EEMD combined with RF and kernel ridge regression model for monthly rainfall forecasts and verified that the hybrid model could attain better rainfall forecast accuracy. ...

Monthly runoff forecasting plays a vital role in reservoir ecological operation, which can reduce the negative impact of dam construction and operation on the river ecosystem. Numerous studies have been conducted to improve monthly runoff forecast accuracy, of which machine learning methods have been paid much attention due to their unique advantages. In this study, a conjunction model, EEMD-SSA-LSTM for short, which comprises ensemble empirical mode decomposition (EEMD) and sparrow search algorithm (SSA)–based long short-term neural networks (LSTM), has been proposed to improve monthly runoff forecasting. The EEMD-SSA-LSTM model is mainly carried out in three steps. First, the original time series data is decomposed into several sub-sequences. Second, each sub-sequence is simulated by LSTM, of which the hyperparameters are optimized by SSA. Finally, the simulated results for each sub-sequence are summarized as the final results. The data obtained from two reservoirs located in China are used to validate the proposed model performance. Meanwhile, four commonly used statistical evaluation indexes are utilized to evaluate model performance. The results demonstrate that compared to several benchmark models, the proposed model can yield satisfactory forecast results and can be conducive to improving monthly runoff forecast accuracy.

Aiming at non-stationary signals with complex components, the performance of a variational mode decomposition (VMD) algorithm is seriously affected by the key parameters such as the number of modes K, the quadratic penalty parameter α and the update step τ. In order to solve this problem, an adaptive empirical variational mode decomposition (EVMD) method based on a binary tree model is proposed in this paper, which can not only effectively solve the problem of VMD parameter selection, but also effectively reduce the computational complexity of searching the optimal VMD parameters using intelligent optimization algorithm. Firstly, the signal noise ratio (SNR) and refined composite multi-scale dispersion entropy (RCMDE) of the decomposed signal are calculated. The RCMDE is used as the setting basis of the α, and the SNR is used as the parameter value of the τ. Then, the signal is decomposed into two components based on the binary tree mode. Before decomposing, the α and τ need to be reset according to the SNR and MDE of the new signal. Finally, the cycle iteration termination condition composed of the least squares mutual information and reconstruction error of the components determines whether to continue the decomposition. The components with large least squares mutual information (LSMI) are combined, and the LSMI threshold is set as 0.8. The simulation and experimental results indicate that the proposed empirical VMD algorithm can decompose the non-stationary signals adaptively, with lower complexity, which is O(n2), good decomposition effect and strong robustness.
